Process technology and Equipment category winners: Exhibitors: Taizhou excellent PU Plastic Mold Co., Ltd. Product Name: Rapid Prototyping Double-station RTM press and molding process

The product uses: electric, pneumatic, hydraulic automation control, rapid, high-quality fiber-reinforced composite products.

The system will be Germany Hp-RTM (high-pressure RTM) (Note: We are the first domestic production of Hp-RTM mold company), vacuum-assisted RTM, SMC molding The advantages of the three kinds of technology combined, integrated into one for the domestic and foreign initiative.

The outstanding advantages of the technology are:

(1) Metal mold, high strength, good mold surface quality. Product quality, accurate and stable size;

(2) A high degree of automation, efficiency is 2-4 times faster than the existing process.

(3) The product quality depends on the equipment guarantee, the worker technical request is low, the general workers can operate, may save the production cost greatly.

This technology is superior to the traditional hand lay-up and vacuum-assisted RTM process and will replace the two traditional crafts in a large area.

Technical Features:

(1) An upper die fixed, 2 lower die (dual-station) automatic switching, upper and lower die in the mold after the injection and curing, workers can be another model to operate, people and equipment are not idle, efficiency multiplied. Short forming period: 30 minutes a product.

(2) Water heating, constant temperature production, quality and stability. Not like the hand paste and other quality by the winter cold effect.

(3) Suction, plastic injection when the upper and lower die separated from a distance, leaving gaps (conducive to pumping gas and resin flow), with 10bar pressure injection, finished with the press will die to the death of pressure, to obtain high-quality surface and dense products.

(4) Configure the modular vacuum system, the injection of glue in the first 10 seconds to quickly exhaust the mold cavity in the air, to obtain a-level surface-free spraying products.

(5) Upper and lower die on the cutting structure, the product does not cut, forming out of the main resin and a small amount of fiber, with a fine file, can be repaired in place without cutting, save a lot of reprocessing costs.

(6) Because the molding pressure is much larger than the hand-paste and vacuum-assisted RTM, so the direct brush can also get high-quality products surface, to avoid the on-site spraying of plastic clothing on the air pollution, environmental health.

(7) Comprehensive advantages, the cost of sharing the mold, the product cost is far lower than the hand lay-up process and vacuum-assisted RTM.

Market evaluation: At the end of May this year, Ningbo molding technology exchange, a large number of Guangdong, Shandong customers contact us, come to visit to negotiate, has been a new launch of multiple orders.
